How did thomas edison invent the light bulb?
The Thomas Edison Innovation Foundation is quick to point out that Edison did not invent the idea of electric light; rather, his contribution was perfecting and making practical the incandescent light scientists had long since tried and failed to reliably produce.CurrentWhile conventional wisdom had convinced scientists that pushing high currents through a low-resistance material was the only way to produce light, Edison turned the notion on its head by using a lower current and a tiny particle of high-resistance material.VacuumThe other vital component necessary for generating light was a vacuum inside the bulb, which had already been proposed by scientists but again was improved upon by Edison. Combining the vacuum with his method of using high current and low resistance, Edison was able to produce light for a continuous 13 hours.Pearl Street StationTo make the light bulb practical outside his laboratory, Edison had to develop a power station to generate electricity, along with the p
